limited within by a moderate tooth. Head at sides moderately deeply sinuate. Beneath head very convex, twice as wide as long, form irregularly hexagonal, posteriorly emarginate at middle, median line with a moderately deep impression at middle. Anterior margin trilobed, median lobe most prominent, with convergent sides and oval tip, lateral lobes triangular, limited behind by an elevated line. There are two pairs of eyes, one each side of the head. The superior eyes are large, prominent and equal in size, one near the posterior angle of the head, the other a short distance in front. The smaller eyes are situated as follows: one moderately convex on the declivity in front of and beneath the upper front eye, the second is on the under side of the head, immediately beneath the front superior eye. It is very indistinct and may escape observation. Antennae arising above and behind the base of the mandibles, four jointed, first joint stout, second longer, equal to the next two together, joints three and four near slender, the terminal one shorter. All joints with moderately long whitish hairs. Mandibles
